Here’s an incident that is only tangentially related to what we’re talking about, but it’s one that I found memorable. My grandmother was reading a tabloid newspaper (which she tends to believe) and it apparently had an article about UFOs. She turned to me and told me that, according to the newspaper, space aliens were real and visiting Earth. Then she went about her ordinary business - the thing about the aliens was simply an interesting bit of trivia for her.

I think her reaction was not in fact particularly unusual, but I found it baffling. The arrival of space aliens would be perhaps the most important thing that has ever happened to humanity. The entire future of the species would hang in the balance, and everything would hinge on what the aliens want. I know my grandmother very well but I still don’t really understand how she thinks about things like this. The best I can come up with is that she believes in many fantastical things and therefore just one more fantastical thing changes little for her.

This isn’t a direct response to what you’re describing but I think it’s relevant as an illustration of one way how the fantastical can be less important than the mundane for people.
